Abstract: An antenna unit includes a dielectric layer through which visible light transmits, a first conductor layer, a pseudo layer, and a second conductor layer provided separately from the first conductor layer. At least part of the pseudo layer is disposed around the second conductor layer in a plan view. The inequality |n1−n2|/N≤1.09×10−1 holds where n1 and n2 (n1 and n2 are integers equal to or larger than zero) are N-level gradation values (N is a natural number) in a case where a first region that exists without overlapping the second conductor layer in the pseudo layer and a second region that exists without overlapping the pseudo layer in the second conductor layer, respectively, in the plan view are read at a resolution of 400 dpi.

Abstract: Low latency of driving assistance is realized in a state where process load on a processor mounted in a vehicle is reduced.
Disclosed is an information processing system, which comprises:



an information processor installed on a roadside, and
a communication antenna installed on the roadside,
wherein the information processor comprises:
a vehicle information acquisition unit to acquire vehicle information relating to one or more vehicles to be assisted located in a coverage area covered by the communication antenna,
a transmit data generation unit to generate transmit data based on the vehicle information acquired by the vehicle information acquisition unit, and
a data sending unit to send the transmit data generated by the transmit data generation unit to the vehicle to be assisted via the communication antenna, and
the transmit data includes at least one of vehicle position information indicating the position of the vehicle to be assisted, and drive control information.

Abstract: An antenna includes a ground plane; a first resonator connected to a feeding point with reference to the ground plane; and a second resonator that is fed power by the first resonator according to an electromagnetic field coupling with no contact. The second resonator includes a first conductor part, and a second conductor part capacitively-coupled to the first conductor part through a gap. A dielectric loss tangent of a substrate part, on which the second resonator is formed, is greater than zero and less than or equal to 0.01.
